11.1.5 Requesting control via a basic function

Enable input "bEnable"

The basic functions "Manual jog

", "Homing" and "Positioning" and the three setpoint followers each

possess an bEnable enable input, via which the control of the corresponding basic function can be

requested.

• If no other basic function and no error status is active, a change-over to the corresponding

function state is effected, and the basic function can be controlled now.

• If several enable inputs are set to TRUE at the same time, the change-over to the function state

is effected with the highest priority.

Status outputs "bEnabled", "bActive" and "bDone"

If the basic function is enabled, the bEnabled status output of the basic function is set to TRUE and

the corresponding drive motion can be started via the control inputs of the basic function.

• If the basic function is currently carrying out a drive movement, this is shown by a TRUE signal

at the status output bActive.

• The basic functions "Speed follower

", "Torque follower", and "Position follower" are only

provided with the status output bEnabled, as the drive directly follows the setpoint selection

after being enabled.

•The basic functions "Homing

" and "Positioning" are furthermore provided with a status output

bDone showing that the drive movement started (Homing or positioning) has been completed.

Re-deactivating the enable of a basic function

When the bEnable enable input of the active basic function is reset to FALSE, the control inputs of

the basic function are inhibited and the status outputs bEnabled, bActive and bDone are reset to

FALSE.

• If the drive is not at standstill, it is brought to standstill within the deceleration time for Stop

if

no other basic function takes over the control of the drive. Here a change-over from the active

function state via the function state "Drive is stopped" back to the basic state "Drive at

standstill" is effected.

• When the enable input of another basic function is set to TRUE, this basic function adopts the

control of the drive immediately.
